Abstract: 1288617 Pinning the bones of meat prior to deboning thereof GEO A HORMEL & CO 10 Nov 1969 54898/69 Heading A2U [Also in Division B8] A pair of articulated bones in a meat portion S, e.g. a shoulder, are pinned together in alignment, prior to deboning by a deboning device 76, by an apparatus 10 comprising a longitudinally slidable table 39 which is reciprocated by a fluid pressure cylinder and piston 40, 41 to cause withdrawal and advancement of a threaded rod 49 which is rotatable by a motor 47 and has a flattened end which engages a slot 33 in a fitting 31 which has been supplied to a support 43 by a shoot 60 having a release slide 63 operating in timed relationship with the movement of table 39, the arrangement being such that the fitting is advanced by movement of the rod 49 and support 43 to cause its shank 36 to penetrate within the outer bone R of the two articulated bones R, H in a meat portion S, the outer end of the bone R having been previously cut off by a rotary power saw 57 moved to and from operative position by a cylinder 59. The end of the meat portion from which the bone R projects is held between clamping jaws 26, 27 during the operations described above, a pivoted table 29 supporting the remainder of the meat portion. After the fitting has penetrated to the joint between the bones, table 29 is pivoted upwardly by operation of a piston and cylinder 30 to align the bones, after which motor 47 is energised and the further advancement of the rod 49 and fitting 31 is controlled by a nut 53, which has a plain bore drilled obliquely to cross its threaded bore, so that the nut can be rocked by a cylinder 56 to dispose either the plain bore (for the initial movement) or the threaded bore (for the final advancement of the fitting 31 to pierce the joint) in engagement with the rod 49. After the bone-pinning has thus been effected, the jaws 26, 27 are opened by operation of suitable means (not shown) so that the meat portion can be hung, by a lower groove 35 in a head 32 of the fitting, on the notched end of a transfer arm 90 which is then swung horizontally to present the fitting to a carrier unit 66 on an endless conveyer chain 67, the carrier unit having a notch to engage an upper groove 34 in the head 32 of the fitting. Subsequently, the meat portion is similarly transferred by horizontally swinging arm 73 to a vertically reciprocating rod 75 adapted to engage the fitting and pull it upwardly through a de-boning iris of the device 76 which removes the meat from the aligned bones, the fitting and attached bones then being engaged by another transfer arm rigid with the arm 77 but above the latter, which transfers it to carriers 78 on a second endless chain 79, the carriers 78 being similar to the carriers 66. Finally, a transfer arm 80, rigid with the arm 90 but at a higher level, transfers the fitting to a gripper 86 which is operated by cylinders 88, 87 to grip and move the fitting into alignment with the upper end of the shoot 60, and then release the fitting so that it enters the shoot and is recirculated.

Filed: 1969-08-12
Abstract: 1318522 Transistor logic circuits RCA CORPORATION 7 Aug 1970 [12 Aug 1969] 40310/69 Heading H3T In a logic circuit the output terminal 20 is driven by Q2A emitter and Q1A collector these transistors being rendered alternately conductive by means such as Q4A, and one of them Q1A having a controlled current path Q8 across its base and emitter controlled via a capacitive coupling Q4B such that Q8 conducts when Q1A turns off. Q8 thus speeds the turning off of Q1A. The logic circuit has two inputs 14, 16 and when one or both goes low the corresponding emitter of Q6 conducts (the corresponding diode of CR1, CR2 having first diverted current through R5 away from Q5A base) so that the input to Q4A falls. Consequently Q1A and Q3 turn off and Q2B and Q2A turn on. The second emitter of Q2B now supplies collector current for Q5A. Positive transients are conveyed by capacitorconnected transistors Q1B, Q4B to Q8 base to speed turn-off of Q1A, Q3. A current regulating transistor Q4C responds to excessive output current through R2 to lower Q2B base and reduce the current. When the inputs 14, 16 go high, Q6 emitters cut off, and its collector conducts to turn on Q4A, the initial current from Q5A emitter transition being supplied from Q2B to speed transition, but Q5A reverting to diode operation as its collector becomes cut off by Q2B second emitter when Q4A collector falls far enough. A capacitor formed by Q5B speeds this change. The base collector diode of Q4C helps to discharge the output 20 as Q4A turns on. Q7 limits input transients. All transistors having the same numerical suffixes have a common collector diffusion in an integrated circuit.

Abstract: 1319572 Automatic flow control IMPERIAL CHEMICAL INDUSTRIES Ltd 16 Sept 1970 [16 June 1969] 30291/69 Heading G3R  In a system in which an analog signal corresponding to the mass of comminuted material in a hopper is converted to a pulse signal, the latter is compared with a reference, any difference being used to control the flow of material from the hopper so as to maintain it constant. In Fig.1, comminuted material 11, such as pigment or anti-oxidant to be used in the production of thermoplastics, is supplied from hopper 10 through an outlet 15 by a screw feeder 12 driven by a motor 14 which also drives stirrers 16. The hopper is suspended at one end of a lever 20 with anti vibration damping, and its tare weight is balanced by a weight 31 at the other end so that the weight of the material acts on a strain gauge load cell 33 or 34 selected according to the range of weight variation. The output of the selected strain gauge, at 38, is thus an analog signal corresponding to the decreasing weight of the material in the hopper and this is amplified by a chopper transistor amplifier and transformed into a train of pulses each of which represents a predetermined incremental change in weight. Sensitivity is increased by dividing the total range of variation in weight into a number of sub-ranges and automatically resetting the input to the transistor amplifier at the end of each sub-range as the output falls to zero. The train of pulses is applied in opposition to a selected D.C. signal representing a desired rate of feed the resultant integrated so that deviation in one sense or the other beyond a predetermined extent operates a reversible two-phase servomotor to adjust a variable speed gear between motor 14 and screw feeder 12 until the feedrate is correct. The signal representing a desired rate of feed may also be in the form of a train of pulses in which case the comparator is an up/down counter. Manual controls, indicators and means to close a valve supplying the hopper when it is full at the start are referred to.
